Unfortunately only eight months kept and now I have to buy a new battery again. The battery suddenly lost power rapidly. 5 days ago he could no longer be fully charged and only came to 91% power. then the battery was drained to about 15% and then reloaded. Now he came only to 71% power. After another empty and then recharge only to about 50% capacity.
A replacement of the defective battery was removed from the market place operator "vhbw - B & W Handelsgesellschaft mbH" rejected on the grounds that the customer has caused the defect, since the article was properly at the factory. I do not know how I as a customer to have this cause, because this battery has been used in my Asus EeePC 1215P from me in exactly the same manner as the original battery; and this has kept this for about 2 years.
There may be in the manufactured products in China a large scatter and I, unfortunately caught a product with very poor quality. Nevertheless, the next battery due to bad experience with Billigheimern will be an original brand battery well again ...
